This video was brought to my attention by 2 other veteran players... who also didnt know.
I've never heard anyone mention it. I've never known about it.
.. and based on the fact that SPB has told me he has a separate keyboard for playing where all of the buttons are right next to eachother, the suspicious activity I saw a week or so ago where I felt like low level macros were being used... it didnt seem out of the realm of possibilities.
But I was also willing to accept it was a bug.. because the game has been buggy as shit for me lately.
